EVAPORA'IIVE COOLER.

To all whom it may concern Be it known that we, JOHN A. l/VALKUP andCHARLES W. VVALKUP, citizens of the United States, and residents ofWaco, Mc- Lennon county, Texas, have invented certain Improvements inEvaporative Coolers, of which the following is a specification.

This invention relates to cooling devices of the general type describedand claimed in a patent granted to John 7. Walkup and Charles W. \Valkupon January 10, 1905, No. 779,823.

An object of our invention is to provide a cooler of the type abovenoted which in addition to being relatively simple and inexpensive toconstruct shall have its parts so arranged as to permit of their quickand convenient assembly or separation; it being es pecially desired thatthe said parts shall be of such form and arrangement as will permit oftheir rapid and compact nesting together to permit of their beingconveniently and safely transported. These objects and otheradvantageous ends we secure as hereinafter set forth, reference beinghad to the accompanying drawings, in which Figure 1, is a verticalsection of a cooling apparatus constructed according to our invention;Fig. 2, is a vertical section on the line aa, Fig. 1; Fig. 3, is afragmentary plan illustrating the detail construction of certainportions of the frame of the apparatus; and Figs. 4 and 5 areperspective views further illustrating certain features of ourinvention.

In the above drawings 1 represents a tray or pan in which the remainderof the apparatus is mounted and said tray is provided with supportinglegs 2 at its four corners. Carried by and detachably fastened to thetray 1 is an upwardly tapering framework formed by four tubular posts 3rigidly but removably connected to the interior of the floor or bottomof the said tray and having their tops rigidly but separably connectedby a cover tray 1 which has the form of a flat container. At each cornerof this cover are downwardly extending projections 5 designed to fitinto sockets 6 formed at the tops of the tubular posts 5. Each of saidsockets usually consists of a metallic strip having its central portionspaced away from but substantially parallel with the cylindrical upperpart of the post to which its end portions are soldered. Each of theposts 3 has a number of projecting pins or lugs 7 Specification ofLetters Patent.

of the posts 3 a fiat plate 14 designed to lie in a plane substantiallyparallel with the bottom of the tray 1 and to be slidable into and outof the socket 13. The cover tray 1 serves as a liquid container and hasin its bottom two upwardly flanged ventilating openings 15 usuallyprovided with screens 16 as shown. The flanges around these openings arepreferably extended to a height above the level of the upwardly flangedsides of the tray 4; as indicated at 17 andthe supporting tray 1 issimilarly provided with an opening 18 through which water falling intoit may be drained into a suitable receptacle or pipe.

Mounted in the cover tray 41 is a baromet ,whereby the container-19 maywithin certain limits be tilted on its rear edge or corner 23 so thatits front edge 24 may be raised to a level immediately adjacent or, ifdesired, above a horizontal plane through the line of the lower edge 25of the inwardly bent side 20.

hen it is desired to use our device a body of relatively thin fabric isplaced around the frame formed by the posts 3 and its upper ends areturned over the top edges of the sides of the cover tray. 1 so as to eX-tend within the same, while its lower edges extend into the supportingtray 1. The container 19 is then filled with water and after the setscrew 22 has been sufficiently extended, is placed in the tray formed bythe cover 4 in the position shown; the outflow of liquid being preventedowing to the fact that the line of the edge 25 is below the horizontalplane extending through the edge 2 1. set screw 22, this front edge 24:may be so lowered as to permit of the entrance of Thereafter by properlyadjusting the small quantities of air below the edge 25 and the liquidin the container 19 is thus permitted to feed into the cover tray at anydesired rate, being thereafter drawn by capillary action into the fabriccover 26 down which it flows into the supporting tray 1. During itspassage down this inclosing cover or fabric a greater or less quantityof the water is evaporated, thereby lowering the temperature of the airwithin the cooler and thus of the articles of material carried by theshelves. By proper adjustment of the set screw 22 the feed of liquid maybe so adjusted that little or none of it reaches the supporting tray 1which, as before noted, may be provided with a receptacle or drainagepipe for carrying off what liqiud does flow into it and out of theopening 18.

For purposes of shipment or other transportation, the various posts 3may be disengaged from the supporting tray 1 by being moved laterallyaway from the sockets 13, while the cover tray 1 may be likewise removedfrom the posts by drawing these latter off of the downwardly projectingparts 5. The various shelves may then be nested and together with thecover tray 1 placed within the supporting tray 1, while the tubularposts 3 are usually of such length that they also may be laid parallelone with the other within the tray 1. The container 19 may thereafter beplaced on the 3 uppermost of the shelves 10 or in the cover tray 4, sothat the whole apparatus when thus arranged for shipment occupies butrelatively little space. Moreover, under these conditions the variousparts are so disposed that the possibility of damage due to roughhandling is reduced to a minimum and as is obvious, it is acomparatively simple matter to reassemble said parts in positions suchthat the apparatus is ready for A use.
